GPU BIOS update problems

[frostbyte3864]

I have 3 Sapphire R9 270X OC 4G GPU's. All had the bios that shows up here that was outdated by 4 upgrades. I downloaded the latest .rom file. Used ATIflash. Backed up. Pointed to the new file. Programmed. Rebooted and the PC won't even boot up. Blue screen says memory dump. This is with two cards installed. Upgraded bios was going onto the not used card, not main. I remove that extra card and it boots up fine. Did it again with the other card with the same result.

Any clue what is wrong? I can't even attempt to use the back up since it won't boot up with the card in that I tried to update.

Care to explain once more? Why did you need to update your BIOS?

My son plays COD. We had it in crossfire mode. It was a little glitchy so I thought I would check for any updates. No problems anywhere else.

To explain again, the current problem is that after flashing, the computer will not even boot up with the newly flashed card installed. On boot up it gives a blue memory dump screen.

What I did before this was to download the latest .rom updated bios file for my cards. Then I used the latest ATIflash program. I made a back up file of the original. Then loaded the .rom file. Rebooted and it wouldn't boot back up.

Well this has been an educational experience.

Solution for anyone who may have the same problem.

When I updated the bios using the tech power file, the good cards went bad. First clue. I emailed the gpu maker, Sapphire. They gave me an email for tech support. They sent me an updated bios and bad mouthed tech power for having a bad file that wasn't approved.

Their file didn't change anything. What I did learn was how to use GPU-Z.

What I was able to do was boot into safe mode. Uninstall the drivers for the GPU's and then I deleted the AMD folder from the C drive. Then when I tried to boot back into windows normally, it found new hardware and did not find the right drivers. It loaded some bad drivers, but it would at least boot into Windows, which it wouldn't do when there were drivers.

Now I can't reboot at this point or it will crash again since there are drivers for the GPU's. But I was able to use GPU-Z at this point. It won't work in safe mode so this did the trick even if it was temporary. With the good card I did not change, I could compare what GPU-Z saw for the bios details. They were different. On a hunch, I used GPU-Z to save the good file. I then made a dos bootable thumb drive and put atiflash on. I put the saved file from the known good card on as well as the files from tech power up and tech support.

I then flashed the card and watched what each file did. For some reason, the cards I have SHOULD work with a different file, but they do not. So they are back working with the original load. In DOS, it shows a file labeled with 2G even though mine are 4G cards and the file from tech power up and tech support both have a load with 4G. Somehow I was given the wrong file for these cards.

So now I can work just as I did before I tried to update the bios. All is good in the world. I learned a lot and I will now try and figure out if somehow the 3 cards I have are not actually what I was supposed to have bought from New Egg.

Probably wrong GPU bios was flashed. Get right GPU bios for your card here: http://www.techpowerup.com/vgabios/
Power off and remove your bricked graphics card from computer so it will boot up staight to built in graphics and you will get a picture. Go in BIOS settings and set your built in graphics as default GPU. Power off and insert your graphics card.
Flash card with right bios or backup. In bios change default GPU to PCI-E slot.
